Symptom: when running programs with high performance requirements, the processor performance drops, even if the temperature low.
Example: when starting a game, the processor starts at 3800 MHz. As soon as it finishes loading, the clock drops to 1800-2000 MHz, even though the processor temperature is at 45-50°C.
What causes the phenomenon: "BD PROCHOT" This is a hidden setting for the thermal protection of the processor. What can trigger this instruction: faulty temperature sensor, faulty battery, faulty power supply. Fortunately, thermal sensor failure is a very rare phenomenon. There are many different test programs for heat sensors and you can also measure the temperature on the heatsink. Without load, the processor and the heatsink are at almost the same temperature. If there is a significant difference then the temperature sensor is faulty. In the event of a battery failure, a battery replacement will solve the problem. In the event of a power supply failure, the voltage measured on the power supply is not suitable for the operation of the laptop. He can't deliver enough power. A consumption meter can be used to make an approximate measurement of whether the power supply is capable of the appropriate performance. With a suitable program, the BD PROCHOT command can be disabled. I don't have a battery in my laptop and this triggered the instruction. It is worth paying attention to the fact that the BIOS automatically turns the command back on after the reboot, which means that every time you turn it on, you have to restart the corresponding program in order to disable it again. If the error has been resolved, BD PORCHOT will be deactivated.
I hope I was able to help others who have a similar problem. In the gaming category, proper maintenance must be done frequently, and then the machine will last a very long time. ROG Strix SCAR II GL504 ROG Strix GL503
